I RAILWAY DUMP-CAR.

To cZZ whom it may concern:

Be it known that I, THOMAS R. MoKNIenr,

a citizen of the United States, residing at Aurora, in the county of Kane, State of Illinois, have invented certain new and useful Improvements in Railway Dump-Oars, of which the following is a specification, reference being had to the accompanying drawings.

on account of the distance between-the tracks My invention relates to railway dump cars, and particularly to cars whose load is discharged by the'tilting of the car-body.

More particularly still, it ,-relates to cars whoseload is discharged from .the sid e of the car when the car is tilted.

- As is well-known, dump cars which ,are adapted to be used upon railroads arelimited in their width to a practically standard width or between the tracks and the siding, in order that cars may not project so far that they cannot pass one another For this reason, when the c ars are tilted laterally to discharge the load, a portion of the discharged load is apt to spread back over the tracks and over the rails. y

It is the principal object of my invention to provide a car whose bottom shall be of the normal or standard width when in carrying position but which may be automatically extended whenthe car is tilted for dum ing so as to form a practical extension of} t e bottom of the car and thus discharge the load in such a way that it will not be caused to slide .or fall backwards over the rails.

To that end, my Invention consists in supplying the discharging edge of the car with an extension so placed that when the car is in of the car in tilted or discharging position,

Fig. 5 is a'detail of the end portion of one of the levers. and the link connection beshowing the position of the various when tilted. Fig. 3is a side view of the tween it and vthe'extending shelf, partly cut Specification of Letters Patent. Application filed December 9, 1907.

Referring to the drawings, 7 indicates the central longitudinal. sill of the car on. which JPatented'May. 26,1908.

are mountedsupports 8.. 9 indicates the car-body from the bottom of which depend a number of pairs of lugs 10 which are pivconnected by means of pins ll with the upper ends of the supports 8, so that the car-body maytilt to one side or the other thereon. The car-body is tilted by any well? known and approved devices, which, being no part of my present invention, are not shown and whose o eration will be readily understood. It is be ieved, therefore that no description of them is necessary.

12 indicates the sides of the canbody. 13 indicates arms which are ivotally connected with the sides 12 near their top edges, and which are pivotally connected with each other at their inner ends by means of a link 14.

15 indicates arms which are pivotally mounted at their upper ends on 'ins 16 which are centrally located at theen s of the car-body 9 and are located above the inner ends of the arms 13. The arms 15 extend diagonally downwards and outwards and are pivotally connected at their outer endswith'i" the sides 12 near the bottom edges of said sides. I

I 17 indicates arms which are pivotally connected at their upper ends to suitable supports 18 at each end. of the car. The arms 17 extend diagonally downward and outward and are pivotally connected attheir outer endsto llnks 19 which extend substantially vertically upward and are pivotally connected at thelr upper ends to the arms 13 at points intermediatethe outer and the lnner ends of said arms 13.

The mechanism thus far above described it is believed that from the above description its operation will be readily understood. When the car-body is tilted to one side or the other, the operation of thesevarious arms is wardside of the car into the position shown my' present mvention, and

. charge edge, and, as is best shown in Figs. 1

and 2, the upper-edge of the a rons and the under edge of the bottom 21 o the car-body are correspondinglly beveled so that when the aprons norma ly hand in a vertical position the beveled edges may be brought together, as is shown in Fig. 1, to prevent excessive jarring or rocking. These aprons extendlongitiidinally the whole length of the of the aprons 20.

discharge edge of the car.

22 indicates supports which are mounted upon and secured to the central sill 7 of the car, and are of sufiicient number to act as proper supports for the mechanism which operates the aprons hereinafter described, and will vary in number, of course, with the length of the discharge edge of the car and 23 indicates arms which are pivotally mounted at their inner ends upon the supports 22. The inner end of the right-hand ar 23 is pivoted to the left of the central line of the support 22 upon one side thereof, and

the inner end of the left-hand bar 23 is pivoted to the right of the central line of the support 22 upon the other side thereof. The bars 23 extend outward and downward and are adapted in their normal osition to rest with their under sides upon t e center sill 7, and are bifurcated as at 24, at their lower ends.

25 indicates pins which pass through the bifurcated portions 24 of the arms 23 at the lower ends thereof.

26 indicates links which are pivotally connected at their inner ends to the bifurcated portions 24 of the arms 23 further away from V dia onally upwards and outwards, are

the ends than are the pins 25, and, extending ota y connected at their outer ends to ugs 27 on the inner or under sides of the aprons 20.

The (izpplration of these devices is as follows en the car is in its normal position, the lower sides of the arms 23 rest upon the top of the center sill 7, and their length and the length of the links 25 are such that the aprons 20 are supported in a vertical pos1tion,that is to say, at right angles to the bottom of the car,so that they do not project beyond the lateral edges of the car. When the car-body is tilted into the position shown in solid lines in Fi 2, the upper apron being prevented from fa ing inwards by the coming together of the two beveled edges above described, the arms 23 and links 26remain in their normal position with reference to the car-body andare carried up with it so that the apron 20 remains in its original position. As the link 23, however, upon the left hand side is revented from descending further by its caring upon the to of the 7 center sill 7-, the tilting of the car-b0 y causes the apron 20 to turn upon its hinge and to be lifted with reference to the car-body into the position shown in solid lines upon the lefthand side of Fig. 2, forming an extension of ,the bottom of the car which throws the matter dumped farther away than it would be thrown if the apron were not there, the top of the apron being brought into approximate alinement with the bottom of the car. When 30 the car is returned to its normal or carrying I position, the apron 20 is restored to its normal position, and the sideportion 12 also is closed upon the car. -When the car is tilted into the other position, it will be readily understood that the apron upon the other side is operated, as is shown in dotted lines in Fig. 2. The aprons 20 therefore, form anauxiliary discharge board, which, in dis-. charging position, becomes substantially an extension of the bottom of the car and what may be called an extension-piece.

The car-body and the aprons may be made of wood as represented in the drawings, or may be made of sheets of steel, if desired.

What I claim as my invention and desire to secure by Letters Patent is g 1. In a dum car, the combination with a tiltable car-b0 y, a side-board, and mechanism adapted to separate the side-board from the car-body on the down side of the car when said car body is tilted, of an extensionpiece located at the dischar e edge of the car-body bottom and normal y held in position in which it does not project beyond the car-body, and mechanism operated by the tiltin of the car-body to automatically project t e extension-Jnece upon the discharge edge beyond such ischarge edge and return the said extension-piece to its normal osition when the car-body is brought bac to normal carrying position.

2. In a dum -car, the combination with a/ 1 tiltable car-b0 y, side boards, and-mechanism ada ted to separate the side boardfrom the car-body upon the lower side of the car when the car-body is tilted, of aprons hinged to the bottom of the car-body on its discharge edges, and mechanism connected with said I aprons adapted to hold the aprons in nonprojecting position when the car is in its normal carrying position and by the tilting of the car-body to automatically swing the apron upon the discharge edge of the car into a osition extending beyond the discharge e ge 12 of the car-body. r
